One of the first questions I'm asked by those who see the Dramble is, "How do I build my own?" Since I've been asked the question many times, I put together a detailed parts list, and maintain it on the Dramble's project wiki on GitHub: Raspberry Pis and Accessories.

For a little over $400, you can have the exact same setup, with six Raspberry Pi 2s, a network switch, a rack inside which you can mount the Pis, microSD cards for storage, a 6-port USB power supply, and all the required cables and storage!
